Extract

A high-power millimetre wave (w1, k1) propagating through a magnetized plasma in the presence of a wiggler magnetic field (0, k0) produces density perturbations at (w1, K1 +K0). The density perturbations couple with the oscillatory velocity at (wl, K1) to produce a nonlinear current at (2w1, 2K1 +K0) driving second-harmonic electromagnetic radiation. The amplitude of the generated wave is sensitive to cyclotron resonance.
